son during the winter months, and one female that he shot from a pepper tree in 

 Los Angeles, November 4, 1901. J. E. Law took several specimens in San An- 

 tonio caiion, October 18, 1903, and L. H. Miller took a specimen in the same 

 locality, December 29, 1904. Several others were seen the same day. C. B. Lin- 

 ton took a pair on Santa Cruz Island, October 21, 1908. 



364. (749) Regulus calendula calendula (Linnaeus). Ruby-crowned 

 Kinglet. 



Breeds in the upper Transition and Boreal zones in the mountains, above 

 7000 feet, south at least to the San Jacinto Range. Abundant winter visitant to 

 the lowlands and the Santa Barbara Islands. Arrives in the lower country dur- 

 ing late September and the month of October, and leaves in March and early 

 April. Extreme migration dates noted by J. Grinnell near Pasadena are : Sep- 

 tember 24 (1896) and April 15 (1896) (Pub. 2, Pasadena Acad. Sci., 1898, 50). 

 In June, 1906. I saw several of these birds at about 9000 feet altitude in the 

 San Bernardino Mountains, but was unable to locate any nests. A. W. Anthony 

 found a nest containing half grown young at an altitude of 9000 feet in the San 

 Jacinto Mountains, July 2, 1895 (Nidiologist, iii, 1895, 16). According to W. 

 O. Emerson, this species is rare in the Volcan Mountains, San Diego County, 

 and perhaps breeds among the firs (Belding, Land Bds. Pac. Dist., 1890, 246). 



365. (749a) Regulus calendula grinnelli W. Palmer. Sitka Kinglet. 



According to the A. O. U. Check-List, this sub-species ranges south in win- 

 ter to middle California. We have one record for southern California, that of 

 a female taken by H. W. Marsden at Redlands, San Bernardino County, March 

 24, 1903 (Bishop, Condor vii, 1905, 143). Now no. 9287 collection L. B. Bishop. 



366. (751a) Polioptila caerulea obscura Ridgway. Western Gnat- 

 catcher. 



Common resident of wooded and brushy localities, from the lowlands up to 

 more than 5000 feet in the mountains. Occurs as high as 7500 feet in early fall. 

 More widely distributed over the lower country in winter, also occurring at this 

 season on the Santa Barbara Islands. Breeds mostly in May. Extreme nesting 

 dates are : Nest containing young birds, noted by J. Grinnell near Pasadena, 

 May 4, 1895 (Pub. 2, Pasadena Acad. Sci.. 1898. 50). and four eggs, fresh, taken 

 by W. M. Pierce in San Antonio Caiion, July 5. 1903. 



367 (753) Polioptila californica Brewster. Black-tailed Gnatcatcher. 



Common resident, locally, on brushy mesas, washes and foothills, north to 

 Ventura County. Breeds most plentifully in May. One of Mr. Brewster's type 

 specimens was taken by J. G. Cooper at Saticoy, Ventura County. November 24. 

 1872, and another was collected by F. Stephens at Riverside, March 28, 1878 

 (Bull. Nutt. Orn. Club vi. 1881, 103). B. W. Evermann found this bird a resi- 

 dent of Ventura County (Auk iii, 1886, 186). I have never heard of its occur- 

 rence in Santa Barbara County, but should not be surprised if it were found to 

 occur there. It is common in certain parts of Los Angeles County at the present 

 time where it was not noted at all a few years back. The first nest and eggs 

 on record was taken by F. Stephens near San Bernardino, May 2, 1887, and is
